RAID Data storage Technology Explained

RAID data storage is a very commonly used technique for maintaining and accessing large amounts of information. Many RAID applications are used on computer servers, even though there are a number of amounts that can be used for desktop applications as well.

Within this article we will look at what exactly RAID is, is raid 0 worth it for gaming , and many more questions what it will and the advantages and disadvantages of working with this technology.

What is RAID?

RAID is an acronym for Redundant Array of Independent Disks. The technique was devised in the late 1980s and is still used today. Essentially, RAID is a way for several disk drives to work together and introduce themselves to an operating system as a single data storage medium.

RAID has essentially 3 goals, to enhance the performance capability of a server or computer, to increase the storage capacity of said computer and also to enhance the reliability of the data saved on it.

Various degrees of RAID accomplish these three goals into a greater or lesser degree depending upon the storage procedure that is used.

RAID Approaches

RAID utilizes a few of basic data storage methods to achieve its goals. The 3 basic data storage methods are mirroring, striping, and parity.

Mirroring is the process of making an identical copy of a set of data and saving it on more than one diskdrive. This gives data redundancy, which protects your data by making it feasible to recover the information from a different drive on your system in the event the original hard drive fails for any reason.

Parity is a method that allows you to rebuild blocks of data in the event of a drive failure. Each degree of RAID utilizes these techniques in various ways to achieve the frequent goal of increased capacity, speed and reliability.

RAID amounts

There are many distinct levels of RAID. The amounts differ from the way that they store and process data and are not to be considered sequential in performance ability. By way of example, RAID 5 is not necessarily better than RAID 1, nor is RAID 100 better than RAID 50. The most frequently used levels today are RAID 0, 1, 5 and 6 along with the nested levels 10, 50, 51 and 60. (We will get to nested levels soon ).

There are seven standard levels of RAID, 0 through 6. Levels 2, 3 and 4 are currently considered obsolete. In addition to these standard amounts, there is rather a variety of non-standard and nested degrees. Low standard configurations comprise degrees such as 7, 5E, 5EE and other exotic combination’s. Nested amounts unite two of the standard amounts to form the nested degree.

RAID 1 and 10 both offer high levels of performance and data reliability, but their storage capacity is relatively low. RAID 5 and 50 are great for reading data, but relatively slow in composing new data into the drives. It has exceptional storage capacity and is a relatively affordable option compared to a number of the other degrees. RAID 5 will be the most popular RAID amount available.
